Sitting on the top of the world! With the property backing directly up to the pristine natural beauty of Chino Hills State Park you have no rear neighbors, ensuring unparalleled privacy and serene, unobstructed views of the hills. One bedroom and a full bath downstairs. Step inside to find a completely turnkey interior that was comprehensively remodeled in 2023. Showcasing new kitchen, new bathrooms, new HVAC system, paint, premium finishes, and modern upgrades throughout—this home is completely move-in ready, allowing the new owner to focus entirely on maximizing the incredible exterior. The true crown jewel of this property is the exceptionally rare, massive flat backyard. In a market where usable land is at an absolute premium, this expansive lot serves as a true blank canvas with limitless possibilities to create your ultimate private compound. Envision designing a custom resort-style oasis complete with a sparkling pool, spa, and an outdoor kitchen, while still having abundant room left over. Plus, the direct proximity to the 14,000-acre state park means outdoor enthusiasts have virtually immediate access to endless hiking, mountain biking, and equestrian trails right in their own backyard. Because of the sheer size and flat topography of the lot, there is ample space to construct up to two Accessory Dwelling Units (ADUs). Whether you are looking to maximize the property's value with substantial rental income, create private guest accommodations, or build a dedicated detached home office and studio, the footprint here can comfortably accommodate your vision. Zoned for the award-winning Placentia-Yorba Linda Unified School District, this location is tough to beat. Beyond the immediate state park access, you can enjoy nearby neighborhood parks, the new Yorba Linda Town Center, and the Richard Nixon Library.
